Component Inspection

Check Fuel Temperature Sensor 

1. IG KEY: OFF, Engine: OFF
2. Disconnect fuel temperature sensor connector B-18.
3. Measure resistance between terminal 1 and 2 of fuel temperature sensor connector B-18.
   1. Specification:
      1. At 0°C (32°F), Resistance 4~7 kΩ
      2. At 20°C (68°F), Resistance 2~3 kΩ
      3. At 40°C (104°F), Resistance 0.9~1.3 kΩ
      4. At 80°C (176°F), Resistance 0.2~0.4 kΩ

4. Is the resistance near the specified value?

   YES

   1. Fuel temperature sensor is OK.
   2. Possibility of defective ECM. Temporarily test with a new ECM and check for proper operation.

      If problem is corrected, replace ECM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

   NO

   1. Test with a new fuel temperature sensor and check for proper operation. If problem is corrected, replace it.

      And go to "VERIFICATION OF VEHICLE REPAIR " procedure.
